STEP 1 - PREPARATION

The watchcase and its components in stainless steel are laying aside the made to measure tools developed especially by the craftsman. At each stage, the dimensions of the components are checked.

STEP 2 - SANDBLASTING AND MICROBLASTING

The watchcase and its components are alternately sandblasted and microblasted by hand using an air pistol. This technique gives a deep grey matte finish to the piece.

STEP 4 - GUNMETAL TREATMENT

A special chemical and thermal treatment, traditionally used for gunmetal, transforms the steel’s silver sheen to a rugged blackened finish.

STEP 5 - POLISHING & BRUSHING

Working with meticulous precision, the craftsman utilizes a range of specialized brushes and diamond pastes. By alternating between polishing and brushing, a subtle, aged look is achieved.
